Mesa 4.0 release notes
September ??, 2001
PLEASE READ!!!!
Introduction
------------
Mesa uses an even/odd version number scheme like the Linux kernel.
Odd numbered versions (such as 3.3) designate new developmental releases.
Even numbered versions (such as 3.4) designate stable releases.
Mesa version 4.0 signifies two things:
1. A stabilization of the 3.5 development release
2. Implementation of the OpenGL 1.3 specification
Note that the Mesa major version number is incremented with the OpenGL
minor version number:
Mesa 1.x == OpenGL 1.0
Mesa 2.x == OpenGL 1.1
Mesa 3.x == OpenGL 1.2
Mesa 4.x == OpenGL 1.3
New Features
------------
Mesa 3.5 already had all the new features of OpenGL 1.3, implemented as
extensions. These extensions were simply promoted to standard features:
GL_ARB_multisample
GL_ARB_multitexture
GL_ARB_texture_border_clamp
GL_ARB_texture_compression
GL_ARB_texture_cube_map
GL_ARB_texture_env_add
GL_ARB_texture_env_combine
GL_ARB_texture_env_dot3
GL_ARB_transpose_matrix
In Mesa 4.0 the functions defined by these extensions are now available
without the "ARB" suffix. For example, glLoadTransposeMatrixf() is now
a standard API function. The new functions in OpenGL 1.3 and Mesa 4.0 are:
glActiveTexture
glClientActiveTexture
glCompressedTexImage1D
glCompressedTexImage2D
glCompressedTexImage3D
glCompressedTexSubImage1D
glCompressedTexSubImage2D
glCompressedTexSubImage3D
glGetCompressedTexImage
glLoadTransposeMatrixd
glLoadTransposeMatrixf
glMultiTexCoord1d
glMultiTexCoord1dv
glMultiTexCoord1f
glMultiTexCoord1fv
glMultiTexCoord1i
glMultiTexCoord1iv
glMultiTexCoord1s
glMultiTexCoord1sv
glMultiTexCoord2d
glMultiTexCoord2dv
glMultiTexCoord2f
glMultiTexCoord2fv
glMultiTexCoord2i
glMultiTexCoord2iv
glMultiTexCoord2s
glMultiTexCoord2sv
glMultiTexCoord3d
glMultiTexCoord3dv
glMultiTexCoord3f
glMultiTexCoord3fv
glMultiTexCoord3i
glMultiTexCoord3iv
glMultiTexCoord3s
glMultiTexCoord3sv
glMultiTexCoord4d
glMultiTexCoord4dv
glMultiTexCoord4f
glMultiTexCoord4fv
glMultiTexCoord4i
glMultiTexCoord4iv
glMultiTexCoord4s
glMultiTexCoord4sv
glMultTransposeMatrixd
glMultTransposeMatrixf
glSampleCoverage
glSamplePass
GLX 1.4 is the companion to OpenGL 1.3. The only new features in GLX 1.4
are support for multisampling and the GLX_ARB_get_proc_address extension.
glXGetProcAddress() is the only new function in GLX 1.4.
Multisample and Texture Compression
-----------------------------------
The OpenGL 1.3 specification allows the multisample and texture compression
features to essentially be no-ops. For example, if you query for multisample
support you'll find none, but the API functions work.
Similarly, texture compression is not implemented by any of the software
drivers but you can specify a generic compressed texture format (like
GL_COMPRESSED_RGBA) to glTexImage2D and it'll be accepted.
Device Drivers
--------------
Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the
device driver. If the driver enables all the ARB extensions which are part
of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3". Otherwise,
it'll return "1.2".
A number of Mesa's software drivers haven't been actively maintained for
some time. We rely on volunteers to maintain many of the drivers.
Here's the current status of all included drivers:
Driver Status
---------------------- ---------------------
XMesa (Xlib) implements OpenGL 1.3
OSMesa (off-screen) implements OpenGL 1.3
FX (3dfx Voodoo1/2) implements OpenGL 1.3
SVGA implements OpenGL 1.3
Wind River UGL implements OpenGL 1.3
GGI needs updating
Windows/Win32 needs updating
DOS/DJGPP needs updating
BeOS needs updating
Allegro needs updating
D3D needs updating
DOS needs updating
The XFree86/DRI drivers have not yet been updated to use Mesa 4.0 as of
September 2001, but that should happen eventually.
Other Changes
-------------
See the VERSIONS file for more details about bug fixes, etc. in Mesa 4.0.
